child components questions

Props (short for properties) are read-only attributes passed to React components. They allow you to pass data and event handlers to child components, enabling component reusability. For example, if you have a `<Button>` component, you can pass text and an onPress handler as props to customize its behavior and appearance.

In Vue.js, `refs` are used to access DOM elements or child components directly. By adding a `ref` attribute to an element or component, you create a reference that can be accessed via `this.$refs` in the Vue instance. This is useful for interacting with the DOM or child components imperatively, such as focusing an input element or calling methods on a child component. However, it is generally recommended to use Vue's declarative features whenever possible and resort to `refs` only when necessary.
